Earthquake rating system
13-Aug-2015 ... On the current logarithmic earthquake scale, a whole number increase, like from 7.0 to 8.0, actually means a 32-fold increase in earthquake ...Building structural systems include beams, columns, shear walls, slabs, and foundations. SPC ratings range from 1 to 5 with SPC 1 assigned to buildings that may be at risk of collapse during a strong earthquake and SPC 5 assigned to buildings reasonably capable of providing services to the public following a strong earthquake.

Pagination. Although you may hear the terms “seismic zone” and “seismic hazard zone” used interchangeably, they really describe two slightly different things.

Earthquake Magnitude Scale. Magnitude scales can be used to describe earthquakes so small that they are expressed in negative numbers. The scale also has no upper limit. Learn more about how we measure earthquake magnitude. Magnitudes are based on a logarithmic scale (base 10).
